To all 2012 am it may concern:

Be it known that we, 'EDWARD B. Hess and LEWIS C. lllrens, citizens ofthe United States of America, and residents of the city of New York, inthe borough of Brooklyn, county of Kings. and State of New York, haveinvented certain new and useful Improvements in Typewriting Machines, ofwhich the following is a specification.

The present invention relates generally to typewriting machines and hasfor its object the production of a spring barrel structure that readilyadmits of being assembled as a unit before the parts are connected tothe machine itself. It consists of the hereinafter described features ofconstruction, a preferred form of which is disclosed in theaccompanying-drawings in which Fig. 1 is a vertical sectional view of atypewriting machine, the section being in a plane back of the key board,showing the relative location of the spring barrel struc- .ture withrespect to the shift rail;

Fig. 2 is a horizontal sectional plan view of a typewriting machine,with parts omitted and broken away, also for the purpose of showin 1 thelocation and arrangement of the spring barrel structure with respect toother parts of the machine;

Fig. 3 is a detail view of the spring barrel and supporting meanstherefor looking from the rear of the machine at a point just within therear framework thereof, that is to say, in the direction of arrow 3 ofFig. 2;

Fig. 4 is a vertical sectional view on the line 4-4. of Fig. 5; 7

Fig. 5 is a sectional view on the irregular line 5-5 of Fig. 3; v

Fig. 6 is a detail sectional View on the line 6-6 of Fig. 5;

F ig. 7 is a sectional view on the line 7-7 in Flg. 5; I

Fig. 8 is a sectional view on the line 88 in Fig. 6;

Fig. 9 is a sectional view on the line 9'--9 in Flg. 5.

This case is a division of application Serial No. 380601 filed May 11,19.20, in which there is disclosed an improvement on the well knownRoyal typewriter that consists mainly in a construction in which thetransversely travelling carriage indicated at 50 sup orts a shiftableplaten carriage 8.

ftable carriage'being raised and lowered by means of shift rail 173actuated by a suitable system of shift key levers that actuate verticallifting arms 180. The transversely travelling carriage is mounted on alower race way 4 suitably supported by the side frames of the machineand connected with the rear wall of the main frame by means of anescapement framing 5 that forms a bridge between the lower race way andthe rear wall of the main frame. The shift rail extends transversely ofthe machine immediately in rear of the lower race way and above aportion of the escapement bridge.

The spring barrel and its supporting means are constructed as follows; abracket consisting of a connecting ortion 265 is provided with twodownward y extending arms 266 and 267, the bracket being secured to therear wall of the'frame by means of screws passing into arm 267. 268indicates a spring barrel shaft mounted in said arms and having anoutboard extension 268 that rejects beyond the arms of the bracket.ounted loosely at the forward end of said, outboard extension is a core269 to which one end of spring 270 is attached, its other end being thespring may be varied in a manner well understood. he adjusting means forthe shaft in this instance are located intermediate arms 266 and 267 andconsist of an upwardly extending screw 275 mounted in an upwardlyextending bushing 27 6' and engaging with ascrew gear 277 carried bysleeve 278 secured to the shaft 268 by screws 279. Consideration ofFigs. 2 and 3 will' demonstrate that the adjusting means for the tensionof the spring is rendered very accessible being, as a matter of fact,directl beneath the left hand rear dust shed of| t e casing. Core 269 isprovided with an extension 280 for the reception of a ball bearing 281,said bearing being held in place by a lock nut 282 engaging a threadedportion of the extension 280. 283 is a cup shaped member of sheet-metalconstituting with a removable plate 284 a spring barrel. Said cup shapedportion 283 is provided with a neck portion 285 secured to one member ofthe ball bearings 281, said ball bearing being in effect housed withinsaid neck portion. A spring barrel gear 286 is suitably secured to thespring barreland engages with the usual pinion-and-ratchet drive mountedon a ribbon feed shaft 287 carried by arm 266 in a manner similar to theconstruction shown in U. S. Letters Patent No. 859,294. 288 indicatesback space-controlling dogs that conveniently find their support on agland 289 that holds them in position against arm 266. Fig. 2 shows thatthe spring barrel shaft extends longitudinally of the machinesubstantially the entire distance between the rear wall of the framework and the shift rail. In order to admit of the removal of such springbarrel shaft, such shift rail is provided with an oversize hole 290 (seeFig. 1) which is axially co-incident with the spring barrel shaft whenthe shift rail is in its upper case position. By this means the sprinbarrel shaft may be withdrawn or inserte through the shift rail. Thebracket that supports the spring barrel structure is provided with abearing 291 in which is hung one arm 292 of a rocking universal frame19; the other end of said frame being supported by a bracket 293 securedto the rear wall of the frame work and carrying an arm 294 of saiduniversal frame.

The shift key lever system herein dis-' closed in part is claimed inapplication Ser. No. 394,672, filed July 8, 1920.

The construction of the shiftable carria e herein disclosed in part isclaimed in app icatlon Ser. No. 404,534, filed August 19,1920.

The feature of providing lower racewa 4 with a central gutter is claimedin application Ser. No. 569,322, filed June 19, 1922.
